Description

Pigment Yellow 17 is a high-performance, diarylide-based organic pigment renowned for its clean, greenish-yellow hue and excellent color strength. This pigment is a critical component for achieving durable, cost-effective, and vibrant yellow coloration across a wide range of industrial applications. It is particularly valued by manufacturers in the plastics, inks, and coatings industries for its reliable performance and good dispersibility. Its chemical stability makes it suitable for demanding processes and end-use environments.

Application

• Printing Inks: A primary colorant for offset, flexographic, and gravure inks, especially for packaging and publication printing.
• Plastics Coloring: Used for mass coloration of polyolefins (PP, PE), PVC, and other polymers for consumer goods, toys, and industrial components.
• Industrial Coatings: Imparts durable yellow color to architectural paints, industrial finishes, and automotive refinishes.
• Masterbatch Production: A key ingredient in the manufacture of color and additive concentrates for the plastics industry.
• Textile Printing: Employed in pigment printing pastes for fabrics, offering good fastness properties.
• Paper Coatings: Used in the surface treatment of paper and board to provide decorative and functional coloration.
